You can get the same effect with a single NIC by using interface
aliases.  But that still won't solve the MythTV problem, since Myth's
database will only have a single IP.

One solution that might work would be to refer to the machine by
hostname instead, then set up each machine's /etc/hosts file to point to
the correct IP for that machine.
